【报Bug】接口返回fail导致整个程序崩溃。

示例代码：

submitOrder2() {
let vm = this;
this.saleOrderParams.productIds = [];
this.saleOrderParams.specs = [];
this.saleOrderParams.textures = [];
this.saleOrderParams.colors = [];
this.saleOrderParams.directions = [];
this.saleOrderParams.markPrices = [];
this.saleOrderParams.sellPrices = [];
this.saleOrderParams.sellCounts = [];
this.saleOrderParams.pcss = [];
this.saleOrderParams.userIds = [];
this.saleOrderParams.dess = [];
this.saleOrderParams.sendTimes = [];
this.saleOrderParams.specialeds = [];
this.saleOrderParams.notes = [];

  if (this.fromProductList.length == 0) {  
    uni.showToast({  
      title: "请选择产品",  
      icon: "none",  
      mask: true,  
    });  
    return;  
  }

      icon: "none",  
      mask: true,  
    });  
    return;  
  }  
  if (this.saleOrderParams.settleMoney > this.totalPrice) {  
    uni.showToast({  
      title: "定金不能大于订单总售价",  
      icon: "none",  
      mask: true,  
    });  
    return;  
  }  
  if (this.saleOrderParams.settleMoney) {  
    if (!this.typeName) {  
      uni.showToast({  
        title: "有定金请选择结款方式",  
        icon: "none",  
        mask: true,  
      });  
      return;  
    }  
  }  
  //合并提交参数

            `?orderId=${res.saleOrder.orderId}`,  
        });  
        // vm.fromProductList = [];  
        // vm.fromDealer = {};  
        uni.$emit("refreshs");  
      }  
    },  
  });  
},

操作步骤：

点击修改，接口返回info=="fail",然后点击页面的任何按钮都会报错。

预期结果：

再次点击应该不报错，能够继续执行。

实际结果：

点击报错后，点任何东西都不能再次点击。
